Sigma Might Soon Release RF Mount Lenses (maybe up to 5 in 2022)

Sigma Canon Eos R Art Prime Rf Mount

A new RF mount rumor and I won’t hesitate to classify it under “good news”. Sigma will eventually address the RF mount.

Latest rumor has it Sigma might dedicate its resources to the design and production of RF mount lenses. Maybe already in 2022. Sigma in then past said that there is not enough demand for RF mount lenses for them to invest into it. In June 2021, Mr. Kazuto Yamaki (Sigma CEO) said that the RF mount is internally discussed and researched. To most of us this sounded like “we are getting into it”. So it doesn’t wonder that much that now Sigma is rumored to release RF mount lenses soon. However, be aware that “Sigma is going to release RF lenses soon”-rumors go back to 2019 (see here too). This time it might be reliable, though.

The source suggests that Sigma might release up to five RF mount lenses in 2022. I can only hope it will happen. Sigma lenses are exceptional performers for the money, I myself love the Sigma 18-35mm f/1.8 and wouldn’t want to miss it. But there are so many more awesome Sigma lenses for Canon cameras.

Stay tuned.

Sigma Set To Release New Contemporary Prime Lenses For FF Mirrorless

Sigma Canon Eos R Art Prime Rf Mount

Sigma seems to be set to release two new Contemporary prime lenses for full frame mirrorless camera systems. For RF mount too?

Nokishita reports that Sigma will release the following two lenses.

  • 24mm f/2 DG DN Contemporary
  • 90mm f/2.8 DG DN Contemporary

Unfortunately, it is not sure they will come for the RF mount too, although they seem to be for full frame systems. Maybe they will be released only for Sony E-mount and the L mount.

Stay tuned.

Sigma Might Make An Important Canon RF Mount Related Announcement Soon

Canon Rf Mount

Sigma might be set to soon announce something important about Canon RF mount lenses (i.e. for the Canon EOS R system).

A new rumor suggests, coming from various sources, that Sigma will soon announce their long term plans concerning RF mount lenses. Moreover, it seems that the development and upcoming release of the Canon EOS R5 might have sped up Sigma’s plans to have RF mount lenses available by 2021.

The interesting part in the rumor is that Sigma will not convert existing ART lineup lenses to the RF mount but come up with an exclusive RF mount lens lineup. And that, in our opinion, is very interesting.

Let’s hope Sigma really comes up with an exciting RF mount lens lineup but we recommend you take this rumor with a grain of salt for the time being.

More RF mount information is listed here.

More to come, stay tuned.

Yet Another Mention Sigma Is Going To Reveal RF Mount Plans Soon

Sigma Canon Eos R Art Prime Rf Mount

We already knew Sigma would make RF lenses. Now another mention surfaced over the web.

We were told Sigma would make lenses for the EOS R back in July 2019. Our source told us Sigma would announce these lenses after they released a bunch of lenses for Sony MILCs.

Latest rumor about Sigma’s RF mount plans has it the company will reveal these plans early 2020. This too fits with our previous rumor. Guess sometimes the Internet silently recycles rumors.

Besides all rumors, you shouldn’t have any doubt that Sigma will jump on the RF mount bandwagon. It’s just plain logic. And that’s great news for all EOS R shooters since Sigma’s recent lenses are nothing less than outstanding.

Sigma Might Release Four Lenses For The Canon EOS R (tell us which one you’d like to see first)

Sigma Canon Eos R Art Prime Rf Mount

Good news for Canon EOS R fans.

In a few weeks Sigma will for the first time announce lenses designed specifically for the Sony Full Frame Mirrorless system. These:

  • 35mm f/1.2
  • 45mm f/2.8
  • 12-24mm f/2.8
  • 24-70mm f/2.8

That’s not the entire story. We have been told (thanks) that Sigma will release these lenses also natively for the Canon EOS R full frame mirrorless system. The source couldn’t tell a timeframe for the RF mount versions. All we know is that they will be released “sometimes later” (i.e. after the release of the Sony versions).

That’s really good news. Sigma makes outstanding lenses and releasing those lenses for the EOS R system will be a great contribution to its lens ecosystem.
